Please say this will end

[DueyCheatemAndHow]

DS (3.5) is getting up at 4.30 every day. We are broken. It's ruining our lives. We've tried EVERYTHING. Please tell me this ends.

Youngest two DC are up between 5 and 6am every day. Youngest will be 5 in a few months.

I am naturally an early riser so used to it now. They don't get to get up and ready until after 6am.

Had blackout blinds for years. Makes no difference.

He needs to go to bed later and no naps.
Yes, you have to keep him awake in the car - singing loudly together does the trick
Bedtime 7.30/8pm.
If you want to sleep (and who doesn't!!) you will have to make changes.
